Quoted from vicjw66:
Coin mechs are the things that make a coin operated arcade game a commercial coin operated arcade game. Without them it is not a commercial coin operated arcade game but rather a game strictly for home use, like a zizzle or Sterns "The Pin".
Zizzle and The Pin do not have coin slots. They are absolutely incapable of accepting coins for coin-op use.
This game has a commerical Happ coin door with coin slots. It's capable of accepting coins for coin-op use. Why is this so hard to comprehend?
